34-Pin BERGSTIK® Breakaway Header for Board-to-Board Stacking
It's RoHS compliant per the manufacturer's listing.
Within the same 95278 base number, the 95278-101-46LF offers 46 positions in the same dual-row, SMT, gold GXT™ configuration — everything identical except the circuit count. The 95278-101-40LF is a 40-position version shipped in bulk rather than bagged. The 95278-102-46LF shares the same 46-position layout but differs in the contact finish thickness or other minor variant — the manufacturer's record shows identical specs otherwise. For a sourcing check, the 95278-101-34LF is the active, RoHS-compliant part with no direct second-source cross-reference on file.
